What is the law if one mentioned one of the foods only in the beginning or only in the end of Meiyn Shalosh?
- Example: One ate Mezonos and drank wine and said Al Hamichya, without saying Veal Hagefen, and in the conclusion, he remembered and said Al Hamichya Veal Hagefen?
If one did not mention one of the foods he ate in the beginning of the blessing, but mentioned it [anywhere] in the conclusion, he nevertheless fulfills his obligation. The same applies vice versa, if it was mentioned in the beginning but not in the conclusion.
What to do initially if remembered in middle: If one remembered prior to saying “Baruch Ata Hashem” in the concluding blessing that he did not say one of the dialects in the beginning of the blessing, he is to retract and repeat from the area of the mistake. If he only remembered after saying Baruch Ata Hashem, it is best to conclude the blessing with only the dialect that he began, and then repeat Meiyn Shalosh for the food that was not included. This however is with exception to one who ate Mezonos and dates/wine and only said Al Hamichya in the beginning of the blessing, in which case he is to conclude also with Al Hapeiros/Hagefen if he remembers.
What is the law if one did not mention one of the foods in Meiyn Shalosh?
- Example: One ate Mezonos and drank wine and said Al Hamichya, without saying Veal Hagefen, what is he to do?
If one did not mention one of the foods he ate neither in the beginning or end of the blessing, then he does not fulfill his obligation of that food [i.e. wine] and is to repeat Meiyn Shalosh for the sake of that food [i.e. Al Hagefen].
Ate Mezonos and dates or wine: If one ate Mezonos and dates or wine, and only mentioned Al Hamichya in Meiyn Shalosh, some Poskim rule he does not fulfill his obligation of Al Hagefen or Al Hapeiros. Other Poskim however rule he does fulfill his obligation.
Ate wine and grapes or raisins: This follows the same dispute as the previous case.
 Piskeiy Teshuvos 208:19
 Sdei Chemed Mareches Brachos 1:20; Mishnhe Sachir 37; Shevet Halevi 3:18; based on ruling in Poskim regarding one who forgot to mention Shabbos in Yom Tov Shemoneh Esrei that he is Yotzei if Shabbos was mentioned anywhere in the blessing. [See Michaber 489:1; Admur 487]

The reason: This applies even according to those opinions who rule that Al Hamichya fulfills the obligation of wine and dates [see Luach 1:17; Omitted in Admur Seder 1:18] and that Al Hapeiros fulfills the obligation of wine [See Seder 1:14; Ketzos Hashulchan 60 footnote 6], as even when one is Yotzei Bedieved with the wrong Nussach, he is only Yotzei if he had in mind to do so for that food. However, here, his intent was to be Yotzei the food he ate and accidently forgot to add the extra Nusach for the other food, therefore he is not Yotzei even according to the above opinions. [See Admur Seder 1:6 and 15]
